The Air-Conditioning, Heating, and Refrigeration Institute launched a certification program for unit coolers, typically used in refrigerated warehouses.
This is AHRI's 39th certification program. Equipment in the program is certified to AHRI Standard 420, Performance Rating of Forced-Circulation Free-Delivery Unit Coolers for Refrigeration.
Unit coolers are factory-made, and include forced air circulation and heat transfer components, to move heat from air to refrigerant, without air resistance from external elements.
